From the morass you are describing here you definitely need a good immigration counsel for your case. If you truly desire completion and serinity to move on with your life, you would retain a professional who would complete th case correctly.
Being in a J-1 status and arriving lawfully with inspection naturally, as you may imagine, does not trigger any inadmissibility if you depart upon your J-1 visa status expiration for one or another reason (termination of employment or earlier departure to the home country for some reasons).
Even if you intent to seek admission to the Unites States eventually you may explain the present situation of compliance with all requirements, which are, arriving lawfully on a J-1, working at the designated place on J-1 leaving upon the visa termination.
One you would be able to explain the circumstances, I do not envision any problems for your admission to the U.S. on any subsequent visas.
